Matty is introduced in the first episode, encountering a distraught Franky in an industrial estate and describing her as "beautiful". The first few episodes portray him as mysterious as he only makes a few brief appearances; his first significant role is in Liv's episode, where he is revealed to be Nick's brother. He and Liv begin a relationship but he cannot ignore his attraction to Franky. He moves back in to the family home, despite his judgemental father. Eventually it seems that Liv cannot handle his feelings for Franky and their relationship is damaged beyond repair by the final episode.
